From The Truth About Guns:

As SIG SAUER’s Chief Marketing Officer, Tom Taylor, told a room full of gun writers, accessory makers and even a few competitors last week, the New Hampshire gun maker wants their modular P320 to be thought of in the same way as the 1911 and the AR-15. They want it to be a “universal” platform around which revolves scores of parts, accessories and add-ons made by custom shops and parts makers all around the country.
